Legal claims defining the scope of protection, as filed with the USPTO.
1. A flash memory storage device for boosting efficiency in accessing flash memory, comprising: a multi-level cell (MLC) flash memory for storing data; a single-level cell (SLC) flash memory for storing data; and a control unit for determining whether to store a file into the MLC NAND flash memory or the SLC NAND flash memory based on the file's data characteristics comprising a size of the file, wherein if the size of the file exceeds a predetermined value, the control unit controls the file to store in the MLC NAND flash memory, otherwise, the control unit controls the file to store in the SLC NAND flash memory.
2. The flash memory storage device as claimed in claim 1 , wherein another one of the file's data characteristics comprises a format of the file.
3. The flash memory storage device as claimed in claim 2 , wherein if the file's data characteristics is a video file or an audio file, then the control unit controls the file to store in the MLC NAND flash memory.
4. The flash memory storage device as claimed in claim 2 , wherein if the file's data characteristics is a configuration file, then the control unit controls the file to store in the SLC NAND flash memory.
